FIRE-SCREEN AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 328,932, dated October2'7, 1885.

Application filed February 26, 1834. Serial No. 122,085.

To all whom it may concern..-

Be it known that I, A. E. FRENoH,a citizen of the United States,residing at East Tawas, in the county of Iosco and State of lWIichigan,have invented certain new and useful Improvements in a FireScreen andVentilator or Air-Girculator Combined; and I do hereby declare thefollowing to be a full, clear, and ex act description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The object of this invention is a fire-screen and ventilator orcirculator of air combined, for saving fuel and adding to the comfort ofg dwellings by drawing the cold air from the floor and allowing the warmair at the ceiling to fall. These results are attained by the mechanismillustrated in the drawings herewith filed as part hereof, in which thesame letters of reference denote the same parts in all the views.

Figure l is a front elevation, partly in sec tion. Fig. 2 is a sideelevation. Fig. 3 is a vertical section.

A A A represent the body of the screen and air'circulator, composed of asheet-metal front, A, affixed to and extending to the edges of the sidepieces, A A, to the rear of which are affixed a transverse piece orpieces, A, about one-half of an inch in thickness, thus forming aninclosure or air-chamber, D, in the lower or wide part of which isa.centrally-located piece, d, to which the front and rear walls aresecured,for the purpose of stiffening the structure and preventing itfrom being warped by heat or other causes. B is a pipe or conduitprovided with a damper, O, having operating-handle O. B is an elbow forconnectingthe ventilator or circulator with (No model.)

the Stovepipe, about eighteen inches above the uptake-opening in thestove, from a position between the stove and the wall, and it should belarge enough to protect the latter from the heat of the stove. It willthus perform the duty of a screen. The metal part A should face thestove.

The operation as a ventilator or circulator is very simple and easilycontrolled. By opening the damper G a cold'air current will be startedinto the stove-pipe, thus causing the fire to burn steadily, and drawthecold air through the air-chamber D'by Way of the flooropenings a, asindicated by the arrows, thus allowing the warm air at the ceiling tofall, the result being a nearly equal temperature in all parts of theroom.

Having explained the construction and op eration of my improvement, whatI claim as new, and desire to secure by Letters Patent, 1s

' The combination,in a combined screen and ventilator, of the case orbody composed of a front screen port-ion, A, sides A, and rear A, theparts being contracted toward their mouth, a pipe-section, B, connectingwith said contracted portion and having an elbow, B, a damper, G, and acentral dividing-piece, d, designed to divide the lower portion of thecasing into distinct apartments,and also to reenforce the front and rearsections to prevent the same from warping.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT EDYVARD FRENCH.
